Hi Berna,<br>
<br>
have you already installed SCIP? If not, a tutorial can be found
here: <a class="moz-txt-link-freetext" href="http://scip.zib.de/doc/html/MAKE.php">http://scip.zib.de/doc/html/MAKE.php</a><br>
<br>
Afterwards, you have to formulate your problem in a file format SCIP
can read. A list of all readable file formats can be found here:
<a class="moz-txt-link-freetext" href="http://scip.zib.de/doc/html/group__FILEREADERS.php">http://scip.zib.de/doc/html/group__FILEREADERS.php</a><br>
<br>
In your case it will be the easiest way to use the lp format. You
can read the description given by CPLEX:
<a class="moz-txt-link-freetext" href="http://scip.zib.de/doc/html/group__FILEREADERS.php">http://scip.zib.de/doc/html/group__FILEREADERS.php</a>. Since your
problem is very small you can use write the lp file by hand. If want
to solve larger problem you should use a modeling language, e.g.,
ZIMPL: <a class="moz-txt-link-freetext" href="http://zimpl.zib.de/">http://zimpl.zib.de/</a><br>
<br>
After you have your lp file (or another file that can read by SCIP)
you should use the interactive shell:
<a class="moz-txt-link-freetext" href="http://scip.zib.de/doc/html/SHELL.php">http://scip.zib.de/doc/html/SHELL.php</a><br>
<br>
Please keep in mind, the mailing list and the community is not here
to do your homework. Before you write a mail please use the search
function:
<a class="moz-txt-link-freetext" href="https://www.google.de/?gfe_rd=cr&ei=ZZhZVrXaJ8OK8Qf0o4awAw&gws_rd=ssl#q=site:listserv.zib.de%2Fpipermail%2Fscip">https://www.google.de/?gfe_rd=cr&ei=ZZhZVrXaJ8OK8Qf0o4awAw&gws_rd=ssl#q=site:listserv.zib.de%2Fpipermail%2Fscip</a>
maybe your problem was already discussed and solved. <br>
If you would like to discuss an approach, found a bug or you would
like to know whether your ideas can be realized with SCIP the
community will try there best to help you. <br>
<br>
Best<br>
Jakob <br>
